25% OFFminimax/minimax-m3

MiniMax-M3 is MiniMax's flagship multimodal foundation model, which MiniMax describes as open-weight. It is built on MiniMax Sparse Attention, which selects key-value blocks to cut long-context compute and supports up to a 1M-token context, and it was trained natively on text and visual data for image and video understanding. MiniMax positions it for long-horizon coding, agentic tool use and autonomous multi-step work such as research paper reproduction and GPU kernel optimization.
